摘要： A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.

摘要： Structures for use in forming products having a wood grain appearance include, for example, a plurality of extruded layers having different colors/shades spirally wound about a longitudinal axis to an outer surface to define the structure. The plurality of extruded layers include varying thicknesses along a spiral length of the plurality of layers and/or portions of the plurality of extruded layers encircling the longitudinal axis include portions disposed at different distances from the longitudinal axis. In some embodiments, the spirally winding includes forming a cylindrical structure, and pressing the cylindrical structure into a cuboid structure having a square or rectangular cross-section across the longitudinal axis and at least a portion of the plurality of extruded layers defining a square or rectangle pattern across the longitudinal axis. Longitudinal portions may be cut from the structures to form the products having a wood grain appearance.

摘要： Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers. The composite structure further has tensile strength and other structural characteristics that allow it to be readily machined into desired storage article forms.

摘要： A manufacturing assembly line for producing an article including a first spray coating station for applying a plastic spray coating to an existing wooden pallet, a second grinding or pulverizing station for reducing the coated article into finely ground particles of a uniform dimension, and a third heating station for converting the mixture into a molten or flowable state. The assembly line further includes a fourth extruder station for forcing the mixture at pressure through an extruder die aperture of a selected cross sectional configured extruder, and so that the mixture is reformed as an elongated article and a fifth cutting station for sectioning the extruded article into selected lengths for subsequent attachment or securernent into a desired configuration.

摘要： The invention relates to a method for making a dimensionally stable wood-thermoplastic composite material composed of a wood component and a thermoplastic component comprising the steps of forming a wood-thermoplastic mass at a temperature above the melting temperature of the thermoplastic component. The mass is then passed through a converging die to form a shaped extrudate profile having a cross sectional shape wherein at least a part of the converging die is maintained at a substantially higher temperature than that of the mass. The profile is then fed through a low friction thermally insulating land section, the land section having the substantially the same cross sectional shape as the exit end of the converging die. The profile is then quenched in a non-oxidizing environment to form a substantially dimensionally stable outer shell around the profile, the shell having a temperature below the melting temperature of the thermoplastic component. The invention also relates to a die assembly for making a wood-thermoplastic composite material.
摘要翻译： 本发明涉及一种用于制造由木材组分和热塑性组分组成的尺寸稳定的木质 - 热塑性复合材料的方法，包括以下步骤：在高于热塑性组分的熔融温度的温度下形成木质 - 热塑性物质。 然后将质量通过会聚模具以形成具有横截面形状的成形挤出物轮廓，其中会聚模的至少一部分保持在比质量的温度基本上更高的温度。 然后将该轮廓通过低摩擦绝热陆地区域进给，该陆部区段具有与会聚模具的出口端基本相同的横截面形状。 然后将轮廓在非氧化环境中淬火以在轮廓周围形成基本上尺寸稳定的外壳，壳体具有低于热塑性组分的熔融温度的温度。 本发明还涉及一种用于制造木质 - 热塑性复合材料的模具组件。
